DAO stack combined with TomasB-C deBruijn mandolins perfect combination crib

With this deck you don't have to memorize the stack! And you don't have to peek at the bottom or top card, you can be across the room!

Spectator cuts the deck three times and six sequential cards dealt. The magician from across the room reveals what the six cards are.

By having mandolin cards where the binary zeros are allows us (magicians) to have a sorted crib sheet telling what the first card of the six is. But normally this required the memorization of a stack in order to identify the other five cards.

Well, we could use Si Stebbins, but for magicians that want a nearly undetectable stack:

The beauty of DAO is that it is a very simple "next card" sequential cyclic algorithmic stack that looks very random. By using DAO this trick is available to magicians who do not have a stack memorized and can use a good looking random deck.

Therefore buy a bicycle Rider back deck and a Mandolin back deck of the same color and then put the entire bicycle deck into DAO order.

Next replace the following positions with Mandolin back cards:
7, 11, 13, 14, 15, 20, 21, 22, 24, 25, 26, 27, 28, 29, 32, 33, 35, 36, 39, 41, 44, 47, 48, 49, 50, 52.

Generic crib for mandolin debruin method:
00=P24 17=P14 40=P23 61=P18
01=P25 20=P22 41=P46 62=P30
02=P47 21=P11 42=P19 64=P09
03=P26 23=P33 43=P12 65=P37
04=P20 26=P39 44=P31 66=P42
05=P48 27=P50 46=P34 67=P05
06=P27 30=P44 50=P10 70=P17
07=P13 31=P29 53=P38 72=P08
10=P21 32=P36 54=P43 73=P04
11=P32 33=P41 55=P40 74=P16
13=P49 35=P07 56=P06 75=P03
14=P28 36=P15 57=P51 76=P02
15=P35 37=P52 60=P45 77=P01

Note the number after the P is the position of the first card of the six cards dealt.

The above two digits that are before the equal sign is an octal code where each digit represents three of the six playing cards. The first card has a potential value of 4, the second card has a potential value of 2 and the third card has a potential value of 1.

They have that value if it is a rider back card otherwise the card has no value if a mandolin back card. Therefore just add up the three cards to get the first octal digit. Then do the same on the second three cards to get the second octal digit.
This is very easy because the maximum value that you could possibly have is 7.

I could have put the DAO cards in the above crib sheet but that would not be ethical because it would reveal the stack and you could probably figure out the algorithm. Therefore I just provided the position number which would work with any stack but since DAO is normally not memorized the above generic crib will not do any good until you replace the P numbers with the actual cards that are in DAO.

If you have the $60 book "calculated thoughts" then the DAO stack is there.
If you don't have that book then I think you can find the DAO stack at a fraction of that cost via "Tricyclic", not sure.

After you buy the DAO stack then on your word processor copy the above crib sheet and replace the above P numbers with the actual DAO card two character name.
Example instead of:
00=P24 17=P14 ...
replace with:
00=6C 17=JS ... and so on.

Then print off the crib sheet small enough to glue on the back of a joker or an ad card.

Now from across the room you can easily and quickly determine the two digit octal code by looking at the backs of the six cards and then while you bend your head down slightly concentrating you look at the ad card crib sheet you are holding in your left hand to determine the first card of the six cards.

Once you know the first card you can mentally figure the rest via the easy DAO algorithm.

Note that it is easy to see the binary code represented by the cards because rider back cards have a bright object in the corners whereas mandolin cards do not. Therefore it is easy to mentally think of the mandolin cards as a binary zero and the rider back cards as a binary 1. So just look at the upper left corner of each card and you have your binary octal codes.

Example: if you see 010 110 which translates to octal 26 then check your crib sheet and you see that octal 26 is the card at position 39 but of course you will have updated/replaced the "39" with the actual card 2 character name on your crib sheet.

Reminder that the three card sequences are dealt as decimal 4, 2, 1 not as 1, 2, 4.
